Dale replied to the thread Undergrad Small question about constantly accelerating charges.This requires the same clarification I mentioned above. How are you detecting the possible electromagnetic wave? IE are you using an... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.Kind of going back to the original question. To understand why gravity is considered a fictitious force ( I prefer the term inertial...

Like.
I personally think that GR's explanation of why ##M_i=M_g## is one of the most intellectually satisfying things in physics. -
Dale reacted to DaveC426913's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with Like.
6000+ exoplanets detected (1988+) Discovery of the Higgs Boson (2012) Accelerating Expansion of the Universe (1998/2011) Quantum...

Dale reacted to Quarker's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with
Skeptical.
It’s been 50 years since any major new developments have occurred. I don’t think there’s any doubt that modern physics exists within a... -
Dale reacted to renormalize's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with Like.
I disagree. Instead, my position is that our current understanding of fundamental physics is close enough to the "truth" that to get...

Dale reacted to russ_watters's post in the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box with Like.
This is a twist on what @Dale said, a fallacy that the box is a constraint or limitation and that therefore ignoring the box increases...

Dale replied to the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box.That is a ridiculous assertion, so I have plenty of doubt about it. What standard are you using to determine a “major” new...

Dale reacted to Pharal's post in the thread Graduate Linearization of the Navier–Stokes equations for real airflow conditions with Like.
How can the Navier Stokes equations be linearized to study real airflow behavior, rather than just small perturbations? Even at speeds...

Dale reacted to Demystifier's post in the thread Undergrad Why is gravity a fictitious force? with Like.
The geodesic equation $$\frac{d^2x^{\mu}}{d\tau^2} + \Gamma^{\mu}_{\alpha\beta} \frac{dx^{\alpha}}{d\tau} \frac{dx^{\beta}}{d\tau} = 0$$...

Dale reacted to Ibix's post in the thread Undergrad How does this configuration not create E field inside the conductor? with Like.
The field lines drawn on the diagram are the lines of the total field, point charge plus conductor charges. Field lines are integral...

Sure he can, just not at rest in a single inertial frame. But he can consider himself to be at rest in a non-inertial frame.

Dale replied to the thread Insights Thinking Outside The Box Versus Knowing What’s In The Box.@Adnorf45, and many of the other people in this thread, are completely misunderstanding the point of the article. The article does not...

Dale reacted to Thor Jackson's post in the thread Graduate Struct parallels between curvature behavior/abstract geometric cycles? with Like.
I think I finally understand the distinction. GR seems to separate two very different kinds of structural behavior: (1) Local evolution...

Dale replied to the thread Graduate Struct parallels between curvature behavior/abstract geometric cycles?.I think this is all covered in the generic term “collapse”, with maybe step (5) excluded.
